What we like, and what we don’t
Worth having

- 2% on gas and groceries ongoing, which is a good rate inside the limit
- Cash back is simple with no programme to learn
Watch out for
- The 2% covers only $500 of combined gas and grocery spending per month, so about $120 a year of bonus cash back

- The $500 cap is shared between gas and groceries, not given to each
- No travel insurance and no purchase protection
- A single household grocery shop can use most of a month's allowance

The earning fine print
Ongoing: 2% cash back on gas and groceries subject to a $500 MONTHLY spend cap, then 0.5% on those categories; 0.5% on all other eligible purchases. Conservative reading: the $500 monthly cap is a single shared cap across gas and groceries combined, which annualises to $6,000 of accelerated spend (recorded in earn_cap_annual) and a maximum of about $120 of accelerated cash back per year. The cap resets each monthly statement period, not annually. For the first 6 months the accelerated rate is 5% instead of 2%, under the same $500 monthly cap. Up to 9 authorized users at no fee.

What the benefits really mean
Purchase Assurance covering eligible items for 90 days, with a $60,000 lifetime limit per account. Extended Warranty doubling the manufacturer's coverage up to one additional year. Trip Assistance, Legal Assistance and Emergency Card Replacement services (assistance services, not insurance). No travel insurance and no mobile device insurance. The 2% gas and grocery rate is capped at $500 of spend PER MONTH, so the maximum accelerated cash back is about $120 a year. The '2%' headline is almost meaningless above modest spend. The base rate is only 0.5%, well below the 1% typical of no-fee cash back cards. The '5%' is a 6-month introductory rate under the same $500 monthly cap, worth a maximum of about $150. The Purchase Assurance $60,000 limit is a lifetime cap per account, not per claim. FX fee is NOT PUBLISHED.
Our verdict
$500 a month across gas and groceries combined is a tight allowance. A family filling one tank and doing two grocery runs is through it, and everything after that earns 0.5%. The realistic ceiling on the bonus is around $120 a year, which is fine for a free card and much less than the 2% headline suggests.
The base rate is the bigger issue. At 0.5% on everything outside the two capped categories, this card is beaten across the board by the free SimplyCash from American Express at 1.25%. The six month 5% introductory rate is worth about $150 and is the main reason to take it. After that, it is a spare card.
